Beyond Willpower: Create a Savings Plan That SticksQapital has automated the savings process based on your habits (because putting money aside isn't one of them).

"Saving money is like adiet -- everyone's going to start tomorrow," says George Friedman, CEO of personal savings app Qapital. "We can't rely on sheer willpower, so we need to have some automation." That comes in the form of specific goals that users set -- say, $5,000 for a trip to Tokyo -- and corresponding rules that save money based on spending habits. Every time you buy a pricey coffee, say, you're "punished" by having money moved into your savings. "But as long as it's going toward a goal you emotionally care about, you're not going to withdraw the money till you hit your goal," Friedman says. Here's a snapshot of the Qapital user.
